I don`t know French to read your note, but your photo has a good idea,but we should not forget about designer of this place,who help for new ideas like yours.
i like your photo composition and happy color of girl`s clothes among cold colors those talk with me about old,hard and far nostalgia that i feel a little heat from too.a girl who play free as a little bird among all of things about past may be she was a symbol of new ages.
i see little green that it grows under the middle sign, a memory from an old green plain maybe that it was a place for girl`s plays,the girl who we can see her in the middle sign.
